Tayghen (original version: Shiltis (シルティス,Shirutisu)) is an Aquos/Ventus hybrid Bakugan, though her appearance leans towards her Aquos side.
Tayghen was created by negative energy in the merged worlds of Aquos and Ventus. The upper half of her body is that of a human girl wearing a dress with very long sleeves and her lower half is that of a giant sea monster. She often overestimates herself.
Complementing her brother Hairadee, Tayghen prefers swimming to flying and uses her Aquos abilities more often than her Ventus ones. Her monstrous lower body might also be a metaphor for her personality, because although her human form looks gentle and innocent, she is quite vicious with a very irritable personality that is so poor-tempered that she will lash out at pretty much anything.
Tayghen appears when the brawlers first enter Vestroia. Initially, she seemed to just be a girl until she revealed her lower half. She and Hairadee face the Brawlers until Shun and Marucho step up to fight them. Marucho soundly defeats her in an underwater battle and hurls her onto shore. However, this proves disastrous, as her Ventus abilities made her far from helpless out of water. Eventually, Shun and Marucho defeat her and Hairadee by teaming up and sending them flying.
Tayghen returns, attacking the human world with Naga's forces until Marucho fights her. Marucho has trouble overcoming Tayghen's double attribute ability until the JJ Dolls appear. The battle continues at a stalemate until Marucho pulls the Aquos quadruple combo. Tayghen is completely overwhelmed by the incredible power of it. Her fate afterwards is unknown.
